Cutting through fog with laser focus

Research from The University of Queensland aimed at controlling light in scattering materials, such as fog or biological tissues, will benefit future biomedical imaging and telecommunications. Optics researchers Dr Mickael Mounaix and Dr Joel Carpenter have found a new way of controlling how light travels through different materials at different times using optical fibres. “The … Read more

Color-changing fiber and theory reveal fundamental mystery of knots

Color-changing fibers and mathematical theory combine to disclose the simple rules that govern the strength and stability of commonly used knots, researchers report. The new study addresses a centuries-old mystery – what makes knots work? Fibers tied into knots and tangles remain one of humanity’s most ancient and enduring technologies and play a ubiquitous, fundamental … Read more

Spectroscopy: A fine sense for molecules

Scientists at the Laboratory for Attosecond Physics have developed a unique laser technology for the analysis of the molecular composition of biological samples. It is capable of detecting minimal variations in the chemical make up of organic systems. At the biochemical level, organisms can be thought of as complex collections of different species of molecules. … Read more

No storm in a teacup – it’s a cyclone on a silicon chip

University of Queensland researchers have combined quantum liquids and silicon-chip technology to study turbulence for the first time, opening the door to new navigation technologies and improved understanding of the turbulent dynamics of cyclones and other extreme weather. Professor Warwick Bowen, from UQ’s Precision Sensing Initiative and the Australian Research Council Centre of Excellence for Engineered Quantum Systems said … Read more

First chip-to-chip quantum teleportation harnessing silicon photonic chip fabrication

The development of technologies which can process information based on the laws of quantum physics are predicted to have profound impacts on modern society. For example, quantum computers may hold the key to solving problems that are too complex for today’s most powerful supercomputers, and a quantum internet could ultimately protect the worlds information from … Read more

Membrane inspired by bone and cartilage efficiently produces electricity from saltwater

Inspired by membranes in the body tissues of living organisms, scientists have combined aramid nanofibers used in Kevlar with boron nitride to construct a membrane for harvesting ocean energy that is both strong like bone and suited for ion transport like cartilage. The research, published December 18 in the journal Joule, overcomes major design challenges … Read more

Demonstration of ultrafast and energy-efficient all-optical switching with graphene and plasmonic waveguides

Nippon Telegraph and Telephone Corporation (NTT, Head office: Chiyoda-ku, Tokyo; President & CEO: Jun Sawada) and Tokyo Institute of Technology (Tokyo Tech, Headquarter: Meguro-ku, Tokyo; President: Kazuya Masu) have demonstrated an ultrafast all-optical switching operation with the lowest energy consumption ever reported for all-optical switching at less than one picosecond (one trillionth of a second). … Read more

Lasing from atomically-thin 2D material heterostructures

The advent of semiconductor lasers revolutionized the way we send, receive, and store information. For instance, the high-speed internet that you are using to peruse this article was made possible by the optical telecommunication network that uses semiconductor lasers and optical fibers to transmit large amounts of data over long distances. Due to their simple … Read more
